STUD 100 Desensitizing Spray for Men - 12g

What is STUD 100 delay spray?

STUD 100 desensitizing spray contains lidocaine 9.6%, a local anaesthetic that helps to reduce the sensitivity of the penis before sex. It's used by adult men who experience premature ejaculation (PE) or find they climax sooner than they'd like.

By temporarily reducing the sensation, STUD 100 can help some men gain greater control over ejaculation. Better yet, it's available without a prescription.

How does STUD 100 spray work?

The active ingredient, lidocaine, is a local anaesthetic. It works by temporarily blocking nerve signals in the skin, reducing how strongly sensations are felt. When applied to the penis, this helps to decrease sensitivity and can delay ejaculation.

How quickly does it work?

STUD 100 is designed to work quickly, so it won't ruin the moment. It should be applied 5-15 minutes before sex, giving the lidocaine time to reduce sensitivity.

How long does it last? 

The exact duration can vary from person-to-person depending on factors like how much spray is used and individual sensitivity. Most men find the effects last long enough for a sexual encounter after applying it 5-15 minutes beforehand.

How effective is STUD 100 spray?

Because premature ejaculation affects everyone differently, results can vary. Some men may find a small improvement, while others notice a more significant increase in control. It may take a few uses to find the number of sprays that works best for you.

Frequently asked questions about STUD 100 delay spray

Which spray is best for erectile dysfunction?

Delay sprays like STUD 100 aren't suitable for erectile dysfunction (ED). They're designed to reduce sensitivity and help delay ejaculation in men with premature ejaculation.

If you're struggling to get or maintain an erection, you may need an erectile dysfunction treatment instead. Medicines for ED, like Viagra and sildenafil, work by increasing blood flow to the penis.

What is better, Viagra or delay spray?

Neither product is better because they treat different problems.

Viagra is used to help men achieve and maintain an erection if they have erectile dysfunction, whereas STUD 100 is used to help delay ejaculation in men with premature ejaculation.

If you're unsure which treatment is right for you, speak to your doctor or pharmacist.

Can I use STUD 100 if my partner is pregnant or trying to become pregnant?

If your partner is pregnant, trying to become pregnant, or breastfeeding, STUD 100 is not recommended.

Do I need a prescription to order STUD 100 spray?

No. STUD 100 is available to buy over-the-counter in the UK, so you don't need a prescription to purchase it.
